I was just wondering what you guys think one of these should go for. It is a 1991 International 4700 with the DT466 engine and a 5+2 transmission. It has 90,000 miles on it, 6 new tires, new brake system in the rear (air), recent paint on the cab, new flatbed body with wood sides, and new steel rear barn doors, and also has a plow frame and hydraulics.
